As you would expect. Of course, only a veteran of these runs could tell you for sure, but I like your chances a heck of a lot better out of CLE than out of EWR. LAS routes do tend to have higher percentages of leisure (read non-elite) pax than many other routes, so you ahve that going for you as well.
